ATTO 75 Patented Mar. 28, 1950 CABINET HAVING COMBINED CLOSURE ANDWRITING TABLE Max Alexander Reens, Bussum, Netherlands ApplicationSeptember 20, 1946, Serial No. 698,210 In the Netherlands September 24,1945 2 Claims.

This invention relates to furniture construction, and more especially toa rotatory device for a writing-table fall board.

One of the principal objects of the present invention is to provide aconstruction in which the fall board can be brought from the closedvertical position into the open horizontal position without making useof conventional hinges.

Another important object is to provide a device of this character bywhich the upper surface of the open fall board is brought in the sameplane with the upper surface of the bottom plank of that partition ofthe writing-table that can be closed by the fall board.

Another object of the invention is to provide a new and improvedconstruction by which the fall board in its closed position is taken upin the inner space through the open side of the writingtable that isclosed by the fall board, in such a way that an even outer surface isobtained and all parts of the mechanism are fully enclosed and invisiblein this position-of the fall board.

A still further object of the invention is to provide a supportingmechanism for the fall board which allows a big load in its openposition without overloading the parts of the writing-tableinterconnected by the rotatory device for the writing-table fall board.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements, combinationsand arrangement of parts constituting the invention and the scope ofprotection contemplated will be indicated in the appended claims.

In the accompanying drawing wherein I have illustrated a preferred formof embodiment of my invention:

Figure 1 shows a vertical section through a part of a partition of awriting-table with fall board in closed postion.

Figure 2 shows a vertical section corresponding to the lower part ofFigure 1 with the fall board in open position.

According to Figure 1 a fall board I closes a space whereof 2 is thebottom wall, 3 the upper wall and 4 one of the side walls. Against theinner surface and near the sides of fall board I two parallel carryingguide rods 5, one of which is visible in the figure, are slidablymounted in guide sleeves 6 fitted on the fall board. The back part ofeach guide rod is bent upward in such a way that it extends into thewriting-table space. The end of this bent part of each guide rod 5 isprovided with a sideways projecting pin 1 fitted in a guide slot 8 of abushing guide 9. The latter is mounted against the side wall 4. Theguide slot slopes upward in backward direction if seen from the frontside of the writingtable.

The top wall 3 is provided with a stop cam ii) in order to fix the fallboard I in its closed position.

Each carrying rod 5 bears between the guide sleeves 6, an adjustablymounted stop plate H, which is fixed in the desired position by means ofa screw bolt l2, extending through an ovalshaped hole of stop plate IIand screwed into rod 5.

In closed position the fall board 1 is taken up in the inner space ofthe writing table between the ends of the walls thereof, of which thebottom and top walls 2 and 3 and the side-wall 4 are shown in thedrawing. All parts of the rotatory device bearing the fall board arefully protected and invisible in this position, which is an importantimprovement compared with the usual hinges.

On opening the fall board I by drawing it out and lowering it, it willfirst move outwards. The pins 1 glide downwards through the guide slots8 and the rods 5 glide downward through the guide sleeves 6. As soon asthe fall board I has left the mouth of the space Within the writingtableit is at the same time turned open and lowered. During this part of themovement the pins 1 turn in the slots 8 and at the same time the rods 5glide further through the guide sleeves 6 until stop plate I l abuts theforemost guide sleeve 6. In the open position of fall board I the backparts of carrying rods 5 rest on the bottom wall 2 of the innerwriting-table space while the pins 1 are pressed against the inner frontsurfaces of the corresponding slots 8.

It is not difficult to choose the dimensions of the parts of therotatory device so that in the open position of the fall board I, shownin Figure 2, the inner surface of the fall board lies in the same planeas the upper surface of the bottom Wall 2 and that the inner edge of thefall board exactly joins said bottom wall.

The load on the fall board I is suspended through the intermediary ofthe sleeves 6 from the carrying bars the latter being supported on thebottom plank "2 of the writing -table along a sufiicient length (fromthe joint between fall board 5 and plank 2 up to the knee of the upwardbend of the rods) to avoid an overloading of of the parts of the writingtable. Any strong stresses at the adjoining edges of the fall board andof the writing-table wall in alignment therewith, such as are caused byknown constructions using hinges, are avoided.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent is:

1. A rotary device for a writing table fall board, comprising twoparallel guide rods each having a bent up leg and an outwardly extendingprojection at the free end thereof, bracket means for slidably mountingsaid rods on said fall board adjacent its side edges with said bent uplegs disposed adjacent the rear edge of said fall board and adapted toextend beyond the rear edge of said fall board, a pair of slotted guidemembers each receiving one of said outwardly extending projections ofsaid bent up legs and adapted to be secured to the opposite inner wallsof a writing table with said slots sloping upwardly and away from saidfall board.

2. In combination a Writing table having walls forming an enclosed spaceopen at one side, a fall board fitting into said open side, a set ofguide sleeves mounted in axially spaced position on the inner surface ofsaid fall board at each 4 of its opposite vertical edges, a parallelguide bar slidably mounted in each set of said guide sleeves and havinga bent up end extending into the space formed by the walls of saidwriting table, an adjustable stop secured to each of said guide rodsbetween its respective sleeves, a transverse pin carried by each of saidbent up ends and extending laterally and outwardly therefrom, guidemembers secured to the inner faces of opposite side walls of the writingtable each with a slot sloping upwardly and rearwardly into saidenclosed space and slidably receiving one of said laterally extendingpins of said guide bars.
